outer surface of the side of the car when in closed position, and whicheifectively serves to render the door opening spark proof so that thepossibility of the contents of the car becoming ignited is substantiallyentirely eliminated.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved flushcar door whereby certain important advantages are attained and thedevice is rendered simpler, less expensive and otherwise more convenientand advantageous for use, all as will be hereinafter more fully setforth.

The novel features of the invention will be carefully defined in theappended claims.

in order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is an elevational view illustrating a cardoor constructed in accordance with an embodiment of my invention and inclosed position, the coacting side of the car being shown in fragment;Fig. 2 is a vertical sectional view taken through the device as dis-Fig. 3 is a view similar to Fig. 2 but illustrating the door in aninoperative adjustment.

As disclosed in the accompanying drawings, 1 denotes a side of the carhaving the door opening 2 produced therein, the walls of the openingbeing stepped, as at 3, to afl'ord a shoulder against which the door Dis adapted to abut, said door being insertible within the door openingfrom the outer side of the car and adapted to have its outer face flushwith the outer face of the side when in applied position.

4 denotes a track-way arranged above the opening 2 and disposedlongitudinally of the side 1 and on which is mounted the carrier 5 andsaid carrier" is provided adjacent its extremities with the dependingstrap 6, the lower extremities of each of said straps being bentbackwardly to afford a guide 7 coacting with the depending flange 8 ofthe track-way, said track-way being substantially T-shape in crosssection. The carrier is also provided with the rollers 9 adapted toengage the track-way inwardly of the 3 upper flange l0.

Pivotally engaged with the door D adjacent its upper extremity are theyokes 11 substantially U-shape in form and heroin disclosed as formedfrom a single length of material, said yokes being pivotally engagedwith the lower ends of the straps 6. The lower edge of the door D isprovided with the recesses 12 in which are adapted to be disposed therock arms 1 1 carried by the rock shaft 15 mounted for axial movementupon the outer face of the side 1 at a point below the opening 2 and theintermediate portion of said rock shaft 15 is provided with theoperating lever 16 whereby it will be perceived that the door D may bereadily forced within the opening 2. It is to be noted that the bottomsof the recesses 12 are formed into the cam surfaces 12 whereby thecontact of the arms 14 therewith serves to elevate the door D and toforce the same snugly within the door opening 2 and it is to be furthernoted that the lower slot of the door opening 2 is provided with the cutout portions 1 1 to ofier no obstruction to the requisite rockingmovement of the arms 14. The arms 14 also afford a means whereby saiddoor may be maintained in closed position and for this purpose the lever16 is provided with the slot 17 to receive the staple 18 carried by thedoor and the free extremity of the lever 16 is provided with the lockingmember 19 pivotally engaged therewith and disposed on such a curvatureas to be directed through the staple 18 to maintain the lever againstoutward movement relative to the door.

Projecting outwardly from the side 1 are the brackets 20 which serve toprevent undue outward-swinging movement of the door D when ininoperative position and the side 1 is also provided with a bracket orstop 21 positioned midway of one of the vertical edges of the opening 2and serving to limit the movement of the door D so as to assure 7 itsproper positioning relative to the opening 2 so that the arms 1 L may beproperly engaged with the door for forcing the same in closedadjustment. I also find it of advantage to have disposed across theupper end of the door the narrow strip 22 which serves to prevent theupper portion of the door D from moving outwardly and thereby thought tobe obvious that a flush car door constructed in acordance with myinvention is of an extremely simple and comparatively inexpensive natureand is particularly well adapted for use by reason of the convenienceand facility with which it may be assembled, and it will also be obviousthatmy invention is suscept ble of some change and modification withoutmaterial departure from the prlnciplcs and splrit thereof and for thisreason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice.
